DHCP Services Blocked by the Firewall RRS feed

  • Question

  • Hi all,

     I installed Windows Vista Server last week. This machine host the DHCP services. I realize that my clients cannot get any IP address.

    After investigating, I concluded that it was the vista firewall that was blocking the requests.

    So here is my configuration :

    • One network interface connected to Internet (mark as public)
    • One network interface that is connected to my intranet (I mark it as private)
    • DHCP (Dynamic Host Configuration Protocol) is allowed in "Inbound rules" of the firewall

     I can get an IP from my DHCP only if I change the state of the public profil in "Windows Firewall with advanced security properties" with Allow for inbound connections.

     Any help ?

     Thank you

    1. Vista Server ?

    2. Vista is a desktop, not server os.  There is no DHCP server built-in to Vista, there is a DHCP client.

    2. There is no need to change the firewall for vista to get a dhcp address

  • what build of longhorn are you using?

    I have not had a issue with the firewall and dhcp on any VIsta builds

  • I use the RC1 (I'll give you the build number later if needed because I don't have access to the server from where I am).

    Just a precision, I don't think it is an issue but just a configuration problem.

  • RC1 is a Vista desktop build there is no dhcp server only a client.

    What the dhcp server that is offering address to client computers

  • so you are using vista as a server ?

    All Vista builds are client not server builds and have no builtin dhcp server.

    so what are using as your dhcp server ?>\

  • I don't know if you are joking or what ...

    Go see this link : http://www.microsoft-watch.com/article2/0,2180,2015214,00.asp

    And please, if you don't know that there is a Vista Server (or Longhorn Server, call it as you want) so you cannot help me.


    I'll try to ask somewhere else ...

  • Sorry but thats longhorn server beta 5600, not vista beta 5600 there is a difference. As for Longhorn beta dhcp server issues


    I would tell you to post you question to http://forums.microsoft.com/TechNet/ShowForum.aspx?ForumID=582&SiteID=17 (the longhorn server support forums)
